Solution

1. Preparation

Gather tools and parts needed for alignment and repairs.
Tools Required:
- Jack and jack stands
- Torque wrench
- Alignment machine
- Basic hand tools (wrenches, sockets)
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported before working under it.

2. Adjust Tire Pressure

Check and inflate all tires to the manufacturer-recommended pressure found on the driver’s door jamb.
Ensure all tires are equal in pressure to avoid pulling.

3. Wheel Alignment

Set Up Alignment Machine:
- Attach the alignment heads to each wheel as per the machine's instructions.
Adjust Alignment:
- Adjust camber, caster, and toe settings to match manufacturer specifications using the alignment machine.
- Tighten all adjustment bolts to the specified torque values.

4. Inspect and Replace Suspension Components (if necessary)

Visual Inspection:
- Look for worn bushings or damaged components in the suspension system.
Replace Components:
- If any components are found to be worn, replace them with new parts.
- Tools Required:
  - Ball joint separator
  - Wrench set
- Follow manufacturer guidelines for part installation and torque specifications.

5. Final Inspection

Perform a road test after alignment and component replacement to ensure the vehicle tracks straight.
Verify that the steering wheel returns to center after turns and that the vehicle no longer drifts.
